Fixing Windows 7 Beta 64bit Blue Screen of Death (BSoD) tdx.sys

I have been using Windows 7 Beta (Build 7000) on my laptop since it became available. I have been very pleased with this new version and looking forward for its RTM. Today, I decided to install Windows Beta 64bit on my desktop machine as well. Everything was fine, until I started getting the following Blue Screen of Death (BSoD):




After some research, I found that the problem is related to my antivirus (AVG Fee) and a network shared drive (DNS323 - Linux based using Samba).

After multiples BSoD, Windows 7 finally suggested a solution to my problem:




The problem occurs because of an incorrect behavior in a system component that occurs when Server Message Block (SMB) connections go over Transport Driver Interface (TDI). My network shared drive uses Samba, which is a reimplementation of SMB. The hotfix can be found at:
This hotfix has not undergone full testing. That is why it is not available under Windows Update. So, it is intended only for systems or computers that are experiencing the exact problem that is described here. You need to register to receive it by email. After installing this hotfix, my problem was solved, and I can finally enjoy Windows 7 Beta on my desktop machine!!
